Abstract

An extrusion puller comprises a long, fixed rail along which a trolley tows the leading end of the extrusion; the traction force for this trolley is provided by one or more linear motors mounted on the trolley and co-operating with the fixed rail. The rail may be of sandwich construction having an aluminium facing between the steel rail and the active surface of the linear motor. The power supply to the linear motor may be regulated by signals from a remote control station in accordance with a force variation device on or near the trolley. Used for all kinds of pulling extrusion, but in particular for aluminium extrusion. The linear motor provides a steady force, which is easy to regulate and is reliable, and also provides a clutch effect.
